[0006] A headrest rod with an insert injection molded wire harness protective sleeve, comprising a headrest rod, an upper protective sleeve, and a lower protective sleeve. The headrest rod is a hollow tube. The upper protective sleeve and the lower protective sleeve are respectively arranged at both ends of the headrest rod. Mortise grooves are provided at both ends of the headrest rod, and tenons matching the mortise grooves are provided on both the upper protective sleeve and the lower protective sleeve.
[0007] Preferably, the upper protective sleeve and the lower protective sleeve are fixedly connected to the headrest rod by insert injection molding.
[0008] Preferably, the mortise grooves are trapezoidal.
[0009] Preferably, the mortise grooves and the tenons are symmetrically arranged.
[0010] Preferably, the mortise grooves are evenly distributed at the ends of the headrest rod.
[0011] Due to the above technical solution, compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. For the headrest rod with an insert injection molded wire harness protective sleeve of the utility model, the plastic upper protective sleeve and the lower protective sleeve are arranged at both ends of the headrest rod, protecting the wire harness passing through the middle of the headrest rod from being damaged, saving space, and having strong operability;
[0013] 2. The headrest rod of the wire harness protective sleeve with insert injection molding of the present utility model, the upper protective sleeve, the lower protective sleeve and the headrest rod are connected by a mortise and tenon structure, and the connection is firm.

[0019] The technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.
[0020] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. It should be pointed out that all the drawings are exemplary representations. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0022] The following further describes the present utility model in detail through specific embodiments in conjunction with the drawings.
[0023] Refer to Figures 1 to 3 , Figure 1 which is a perspective view of the present utility model, Figure 2 is Figure 1 a partial enlarged view of part A in Figure 3 which is an exploded view of the present utility model. A headrest rod with an insert injection molded wire harness protective sleeve provided by the present utility model includes a headrest rod 1, an upper sheath 2, and a lower sheath 3. The headrest rod 1 is a hollow tube to facilitate the threading of the wire harness. The upper sheath 2 is arranged at one end of the headrest rod 1, and the lower sheath 3 is arranged at the other end of the headrest rod 1. The upper sheath 2 and the lower sheath 3 are both hollow structures to facilitate the threading of the wire harness. Mortise grooves 11 are provided at both ends of the headrest rod 1, and tenon heads 4 matching the mortise grooves 11 are provided on the upper sheath 2 and the lower sheath 3. The arrangement of the mortise grooves 11 and the tenon heads 4 can firmly fix the plastic upper sheath 2 and lower sheath 3 to the metal headrest rod 1.
[0024] In one embodiment, the upper sheath 2 and the lower sheath 3 are fixedly connected to the headrest rod 1 by insert injection molding, that is, the formed headrest rod 1 is placed in an injection mold, and the plastic upper sheath 2 and lower sheath 3 are fixed to the headrest rod 1 by insert injection molding. The plastic upper sheath 2 and lower sheath 3 can separate the wire harness from the sharp edges of the headrest rod to prevent the wire harness from being scratched.
[0025] In one embodiment, the mortise groove 11 is trapezoidal, and the mortise groove 11 and the tenon head 4 are both symmetrically arranged.
[0026] In one embodiment, the mortise grooves 11 are evenly distributed at the end of the headrest rod 1, and the tenon heads 4 are evenly distributed on the upper sheath 2 and the lower sheath 3 corresponding to the mortise grooves 11.
[0027] The following will refer to Figures 1 to 3 to illustrate the working principle of the present utility model.
[0028] Connect the headrest rod 1 with the upper sheath 2 and the lower sheath 3 to the headrest. The wire harness passes through the headrest rod 1 into the headrest. When passing the wire harness, the upper sheath 2 and the lower sheath 3 can isolate the wire harness from the sharp edges of the headrest rod 1, preventing the wire harness from being cut, and it has strong operability.
[0029] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should be covered within the protection scope of the present utility model.
